Retaining chmod permissions for scripts in git repositories

git update-index --chmod=+x your_bash_script.sh

The git documentation provides more information on the update-index command here: https://www.git-scm.com/docs/git-update-index

Clone repository including all submodules

Get the latest commit in the parent repository:

git clone {repository_url}
cd {repository_dir}
# -- OR --
git pull

And then update the submodule:

git submodule update --init --recursive

This should pull the relevant commit for the submodule, but it will be in detached HEAD mode based on the commit of the submodule reference in the parent repository.

Revert without commit

A standard git revert will create a new commit with the reverted content. To revert without creating that commit:

git revert {commit-id} --no-commit

The changes will be staged ready for committing, but a git reset will unstage the changes, so you can continue making changes.

What about merges?

You’d need to provide further commands to do this, as follows:

git revert -m 1 {commit-id} --no-commit

The -m identifies that it’s a merge commit that you’re reverting, and the number 1 indicates that you want to revert back to the tree of the first parent prior to the merge.

Revert a range of commits

git revert {oldest_commit}^..{newest_commit}

i.e.

git revert abcdef01^..abcdef09
